Product Overview
Water circulation risers and primary thermal skids use the Grundfos NB 80-200/164 end-suction pump. Fitted with a 2.2 kW motor, system piping interfaces through an axial DN 100 suction port and a radial DN 80 discharge flange.
Operational throughput rating attains approx. 1545 L/Min liquid movement and overcomes a approx. 8.5 m maximum head. Housing construction features cataphoretically coated EN-GJL-250 cast iron, accommodating a stainless steel impeller and a BQQE mechanical seal. Net weight measures 94 kg.
Powered via a 415 V three-phase feed, the unit consumes 4.5 Amps rated current for 2.2 kW output. Fluid temperature capabilities range from -25°C to 120°C under working pressure limits up to 16 bar. Flange interfaces are dimensioned at DN 100 inlet and DN 80 outlet.
Drive casing protection conforms to IP55 environmental criteria, using Class F insulation. External motor overload protection must be provided by the installer. The back-pull-out construction allows extraction of the motor and rotating components without disturbing suction or discharge pipe connections.
Features
- Solid stub shaft and ball bearing arrangement counteracts operating mechanical stresses.
- Standardized PN16 dimensions per EN1092-2 align with facility pipe headers.
- IEC standardized electric drive rated for continuous S1 operation in ambients up to 40°C.
- Back-pull-out arrangement allows fast access to motor and impeller without disturbing pipework.
- Precision balancing of rotating parts delivers quiet, low-vibration fluid transfer.
- Heavy-section cast iron volute with integral mounting pads provides solid base support.
- Replaceable wear rings protect casing hydraulics and retain designed pumping clearances.
